Output current: 20A MAX , More than 15A, please strengthen the heat dissipation (related to the input and output voltage difference, the larger the differential pressure, the smaller the output current)

Since the input current is 30A at 10-30V and the input current is 25A at 31-60V, the output power is related to the input voltage. The higher the input voltage, the higher the power.

(Input voltage * input current is equal to the whole machine power) For example, the input 12V*30A power is 360W. The input 24V*30A is 720W. When the input voltage is 36V, the input current is 25A. The maximum power is 900W.

Voltage regulation:

When the power supply is unloaded, use a flat-blade screwdriver to adjust the output terminal "V-ADJ" potentiometer clockwise to increase, counterclockwise to small, due to the large output capacitor capacity, the output voltage is adjusted from high voltage to low voltage. The reaction will be slower. The adjustment of the instrument is smaller. (The default output voltage is adjusted to 19V)

Current regulation:

Adjust the "CC A-ADJ" potentiometer counterclockwise for about 30 turns, set the output current to the minimum, connect the load such as the LED battery, and adjust the "CC A-ADJ" potentiometer clockwise to the current you need. For battery charging, after the battery is discharged, it is connected to the output, and adjust the CC A-ADJ to the current you need. When charging, be sure to use the discharged battery to adjust the battery. The more the charge, the smaller the charge current. The default output is ESC to 3A. (Do not adjust the current by short-circuit output. The circuit structure of the boost module cannot be adjusted by short circuit.)

Input low battery protection adjustment:

The low battery protection is mainly for preventing the battery from being over-discharged when the input power is the battery, the power module and the battery will be damaged if the battery voltage is too low. When the input is the switching power supply, the low voltage protection should also be set.

Method 1: For example, set 12V battery low battery protection. Connect a 10V voltage to the input terminal of the power module. Use a flat-blade screwdriver to adjust RV1 (clockwise protection voltage value is increased, counterclockwise protection voltage is turned down) until the UVLO lamp is on. At this time, the low battery protection voltage is 10V. When the voltage drops to 10V, the power module does not rise (the input voltage is equal to the output voltage). Only after the input voltage is higher than 10V, the power supply starts to resume boosting.

Method 2: Input the battery or switch power supply. If the UVLO lamp on the board is off, adjust the RV1 potentiometer counterclockwise to brighten the UVLO lamp, and then turn it clockwise two turns. If the UVLO lamp is on, turn the RV1 potentiometer clockwise, turn off the UVLO lamp, and then turn it two turns. (Adapt to 8V-45V voltage)
